Natural outcrossing in spaced planted F₂ populations and solid seeded advanced generations of wheat (Triticum aestivum L. em Thell)

Creator:: Boinnet, Jerry K. K.
Abstract:: This study was conducted to investigate the possible contamination of foreign pollen at different stages of a wheat breeding program. These included spaced planted F₂ segregating populations, replicated yield trials and seed multiplication. The experimental wheat materials consisted of four different F₂ populations, four cultivars and two experimental lines. Two...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

Prediction of kernel hardness and grain protein based on the performance of F₃ and F₄ populations derived from ten wheat crosses (Triticum aestivum L. em Thell)

Creator:: Hazar, Necati
Abstract:: Ten wheat crosses (four winter x spring and six winter x winter) involving F₃ and F₄ generations and their respective winter parents were used to determine whether the early generation selection would be effective for kernel hardness and grain protein content. In 1980, twenty individual F₂ plants were selected with...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Response of grain yield, plant height and kernel weight in three winter wheat crosses (Triticum aestivum, L. em Thell) to different methods of selection

Creator:: Salmeron-Zamora, Jose Juan
Abstract:: This study was undertaken to see if a method of handling segregating populations could be employed which combined the positive attributes of the traditional pedigree and-bulk methods. Derived F₅ lines from the pedigree, bulk, and what is identified as a modified bulk method, were obtained from three winter wheat crosses....

Gluten protein polymeric composition and allelic variation as related to bread-making quality in durum wheat (Triticum turgidum L. var. durum)

Creator:: Ammar, Karim
Abstract:: Attempts to develop dual-purpose durum wheat cultivars for both pasta and bread-making have been unsuccessful. To better understand this limitation, thirty durum genotypes, selected based on their diverse geographical origin, and five bread wheat cultivars were compared as to their flour mixing properties, dough physical characteristics and baking performance. The...

Yield loss assessment in nonprotected winter wheat varieties (Triticum aestivum, L. em Thell)

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates. Within each planting date, varieties were grown under four different combinations of two soil treatments (fumigation and nonfumigation) and two foliar treatments...

Influence of chelating agents on genetic recombination of Zea mays L.

Creator:: Ihrke, Charles Albert
Abstract:: Crossover frequencies for seven selected regions on five chromosomes of maize were measured to ascertain the effect of chelating agents on recombination. Ethylenediamine tetraacetic acid, EDTA, and dimethyl sulfoxide, DMSO, were used in three concentrations singly, and in all combinations. Plants heterozygous for for linked genes governing seed and seedling...

Possible associations between three procedures to measure noodle starch quality in winter wheat (Triticum aestivum L.)

Creator:: Weight, Chris (Christopher Thompson)
Abstract:: Until recently, the viscoamylograph had been the primary method for measuring starch as it relates to noodle quality in wheat. This method requires a large sample of flour and is time consuming. With the introduction of the rapid visco-analyser (RVA) in 1986 and the more recent flour swelling volume procedure,...
